Abb pse105-600-70 Soft Starter 104 Fla Motor Control

Product Description

The ABB pse105-600-70 is a compact PSE Series soft starter designed to control motor acceleration and deceleration in AC motor-driven systems. It accepts motor voltages from 208 to 600 volts AC and control voltages from 120 to 240 volts AC. Rated for 104 full load amps (FLA) under normal duty and 80 FLA under heavy duty operation, this unit delivers controlled ramp-up current to reduce mechanical stress and inrush current at startup. It ships with a digital keypad, optional fieldbus communication capability, integrated overload protection, and a built-in bypass contactor. Installation is via screw mount.

The pse105-600-70 is suited for commercial and industrial pump and motor applications where network capacity is limited or where load variation requires active current management. The integrated current limit function provides control over motor behavior during starting, making it practical for installations involving pumps subject to overload and underload conditions. Licensed electricians and motor control technicians typically handle installation in accordance with applicable NEC guidelines and local electrical codes.

Key Features

• Normal duty rating of 104 FLA supports a wide range of motor sizes
• Heavy duty rating of 80 FLA for demanding load cycles
• Motor voltage range of 208 to 600 volts AC for broad system compatibility
• Control voltage range of 120 to 240 volts AC
• Built-in overload and underload protection for pump-specific fault coverage
• Includes digital keypad and optional fieldbus communication for integration into control networks
• Integrated bypass contactor eliminates the need for a separate bypass component

Compatibility

Designed as an OEM-style soft starter replacement or new installation component for AC motor-driven equipment operating within the 208 to 600 volt AC motor voltage range, including pump and fan applications in commercial and industrial settings.

Installation Notes

Installation should be performed by a licensed electrician or qualified motor control technician. Disconnect and lock out all power to the motor circuit and control circuit before wiring or mounting. Follow NEC Article 430 requirements for motor branch circuit protection and conductor sizing. Do not bypass or defeat the integrated overload protection function after installation.
